It's been longed rumored that Microsoft was going to make the Zune software compatibile with Apple's desktop OS, but the question still remains when? While we still don't know the answer to the latter question, we now know officially that Microsoft is making the Zune software Mac friendly syncing possible between Windows Phone 7 and a Mac (see Update 2, below).

In a Tweet that was posted (and quickly deleted), Oded Ran, Head of Consumer Marketing, Windows Phone, UK, basically announced that Mac users will be able to use Zune on their computers with "more details soon" as a tease.

Offering such compatibility between Macs and Windows Phone 7 is important to take the fight to Apple, we suppose, though it's unclear how many Apple fans will really ditch their iTunes/iPhone mini-closed empire for the "enemy's offerings". In that sense, this move is probably more symbolic than strategic in the long run, but it's one of those things that is very symbolic. Plus we know there has to be a few Apple fans who want Windows Phone 7, right?

Update: Evidently Microsoft decided to reveal a little bit more stating "Later in 2010 Microsoft will make a public beta available of a tool that allows Windows Phone 7 to sync select content with Mac computers."

Update 2: And it's not Zune software, according to Thurrott, but a way for Mac users to sync content to their devices. Ah, the finer differences in life.
